BRICK-MOLD.

SPECIFICATION forming part of Letters Patent No. 630,114, dated August 1, 1899. Application filed January 16, 1899. Serial No. 702,332. (No model.)

i To all whom it may concern: vidingthe vent-openings necessary to relieve Be it known that we, OLIVER H. ROOT, rethe brick from being held in by suction, but siding at Indianapolis, in the county of Maralso having a tendency to start the brick out ion, and GRAFTON E. LUOE, residing at Brazil, of the molds, and this Without causing any 5 in the county of Clay, State of Indiana, citiroughness at the corners or front edges, but zens of the United States, haveinvented ceronly along the middle portions, where, as tain new and useful lmprovementsin Brickabove stated, it is not objectionable, but Molds, of which the following is a specifi'carather advantageous. tion. In the accompanying drawings, Figure l is 10 As is wellknown,itis necessary to have venta perspective view of a brick-mold structure openings in the bottoms of brickmolds in orcontaining molds for six brick, and which is der that the bricks can be readily removed generally of an ordinary and well-known therefrom. Openingsat the corners of such" form, but inrwhich the bottoms of the mold molds as have heretofore been used have a structure are formed in accordance with our tendency to leave the corners of the bricks present invention; and Fig. 2 is a longitudisomewhat rough and ragged, so that a secnal sectional view, on an enlarged scale, ond operation,known as pressing, hasbeen transversely of one of the molds and includnecessary where smooth symmetrical sightly ing fragments of two adjacent molds, illuswork is required. \Vhere the bottoms are trating our said invention more clearly. 7o 20 severed from the sides and partitions at the These mold structures consist, as usual, of corners also, they are apt to spring away, thus the side members 1 and 2, a suitable number producing some variation of the dimensions of transverse partitions 3, which form the of the brick and causing inequalities, so far sides of the individual molds, and pieces 4, as straightness and evenness are concerned. which also form the handles to the mold struc- 7 5 3 To construct separate valves is somewhatextures, and bottoms composed of parts 5 and pensive, besides which said valves frequently .6, the edges of which are beveled, as shown, become clogged and inoperative.

The botopenings through the bottom are vertical,then tom portions 5 are nailed strongly to the sides that portion of the bottom between the slits 1 2 and partitions 3, and thus, as will be read- 0 is wholly unsupported and may spring down ily seen, the corners of the molds at the hoti a greater distance than is permissible with toms of the partitions 3 have no openings or perfect Work. However, some springing irregularities whatever, while the parts 5, down of a central portion is not disadvantawhich form a portion of said corners, are geous, as slightroughness onthc sides of the strong and rigid and unyielding.

The slits 7 are comparatively tom in parts divided by slits running lengthnarrow, and under the pressure of filling the 0 o wise of the several mold-cavities, said slits molds said slits are nearly closed, while when being at a point back from the edges or corthe pressure is relieved they reopen and start ners of the mold, and also arranged at an the bricks out of the molds. Too great a angle or diagonally to the mold-opening. movement of these parts 6 is prevented by With such slits the tendency when the clay the edges of the parts 5, which extend under 5 5 is pressed into the molds is to spring the them, as clearly shown in Fig. 2, and with central portion of the bottom downwardly which said parts 6 will come in contact after somewhat, causing the slits to partially or but a comparatively slight movement and be wholly close while the pressing operation is thus supported. going on, while when the pressure is relieved It is of course obvious that where desired o the inherent spring force of these parts tends the bottom piece 6 maybe made in two or to return them to position, thus not only promore parts with narrow slits between the several parts, especially where it is desired, as in the cases of extra-large brick or some peculiarly adhesive clays, to supply a greater number of vent-openings. These, however, are mere mechanical details of arrangement and construction and are, of course, comprehended in our invention.

Having thus fully described our said invention, what we claim as new, and desire to secure by Letters Patent, is

l. The combination, in a brick-mold, of the usual sides and ends, bottom pieces 5 rigidly secured thereto and forming the corners to the molds, and other bottom pieces 6 secured by their ends to the side pieces of the mold structure, narrow slits being left between said bottom pieces 6 and said bottom pieces 5, substantially as set forth.

2. The combination, in a brick-mold, of the usual sides and ends, bottom pieces 5 rigidly secured thereto and extending across the partitions dividing the several molds and forming square and unyielding corners for said molds and having their edges also extending outwardly, and central bottom pieces 6 secured only by their ends and having their upper edges extending over the outwardlyextending lower edges of the bottom pieces 5, thus leaving diagonal slits between said two bottom pieces, and said bottom pieces 5 thus being adapted to support the edges of said bottom pieces 6 when the latter are pressed downwardly, substantially as and for the purposes set forth.

In witness whereof we have hereunto set our hands and seals, at Brazil, Indiana, this 10th day of January, A. D. 1899.
